Four such microgrids have been setup at BYPL offices in east Delhi to demonstrate the technology. The energy generated through the rooftop solar caters to the internal power requirements of office loads and charges the batteries. The surplus is fed into the grid, which has the potential to reduce electricity bills.

According to experts, these microgrids have multiple benefits, both for the consumer and the discom, like — preventing outages by sharing the load with distribution transformers (DT), power availability even in case of an outage from the main grid, auto demand response in case of peak power, reduction in energy bills etc.

SCIENCE AND TECHNOLOGY

1. The starry dwarf frog, named after Wayanad’s Kurichiya tribe, is found outside protected areas

It is just 2 cm long and sports pale blue spots and brilliant orange thighs.

The discovery of the starry dwarf frog, a nocturnal amphibian that lives under leaf litter on a mountaintop in Kerala’s Wayanad, has been published on March 13 in PeerJ, an international multidisciplinary journal.

a. Key facts

It was in June 2010 that frog researcher Vijayakumar S.P. first laid his eyes on the odd-looking frog and picked it up from a top Wayanad’s Kurichiyarmala.

He knew that it was a new species, it had many interesting morphological characters like shape and colour patterns that people haven’t seen in other Western Ghats frogs.

Long-term exposure to the major air pollutant PM2.5 increases the risk of diabetes, an international study conducted in China has found.

Experts from the Fuwai hospital in Beijing under the Chinese Academy of Medical Sciences and Emory University in the US evaluated the association between long-term exposure to PM2.5 and diabetes incidence based on data collected from more than 88,000 Chinese adults.

a. Key facts

The large-scale study conducted over a decade found that the risk of the disease increased by about 15.7% for an increase of 10 micrograms per cubic metre of longterm concentration of the pollutant, considered one of the worst.

The adverse effects of PM2.5 were larger among young-to- middle-aged subjects, females, non-smokers and subjects with lower body mass index as per the study.

China is said to have the largest number of diabetes patients in the world.

It also has a relatively higher concentration of PM2.5 in the air despite improvement in air quality in cities like Beijing in the last few years.

Even though there are no India-specific long-term studies, the co-relation will be more or less the same as far as India is concerned because pollution is severe in India and both Indians and Chinese people are pre-disposed to diabetes.
